v Specification of Letters Patent.

Application filed June 25, 1918. Serial No. 775,644.

To all whom it may concern:

Be it known that I, JAMES F. MACWIL- LIAM, a citizen of the UnitedStates, residing at Worcester, in the county of Worcester and StateofMassachusetts, have invented a new and useful Cop-VVinder, of which thefollowing is a specification.

This invention relates to a cop winder of the type in which the yarn isfed through a traversing guide to a conical cop former and in which thecop is wound upon a spindle rotating within the former. In machines ofthis type heretofore used it has been the common practice to mount thecop former rigidly upon the frame of the machine. This construction hasbeen productive of more or less inconvenience and difliculty in removingthe cops from the machine, and specially constructed spindles have beenrequired in order to permit the dotting to be accomplished.

It is one of the objects of my invention to provide a machine in whichthe cop former is movably mounted so that it may readily be removed fromoperative position when it is desired to doff the spindle.

Another object of my invention is to provide a machine in which eachspindle may be disconnected from the common driving means independentlyof the remaining spindles.

A still further object of my invention is to provide a machine having amovable cop former in which movement of the former from operativeposition will disconnect the spindle from the driving mechanism.

With these objects in view my invention contemplates the construction ofa machine in which the cop former is pivotally mounted for verticalmovement and is held in operative position by a manually movablesupporting member. Each spindle is provided with a separate drivingpulley and with clutch mechanism by which the pulley can be disconnectedfrom the spindle at will. Connections are alsorprovided' between themovable cop former and one member of the clutch mechanism whereby theremoval of the former from operative position will disconnect thedriving mechanism;

My invention further consists in certain devices, combinations andarrangements of parts which will be" hereinafter described and morefully set forth in the appended claims.

A. preferred form of my invention is shown in the accompanying drawings,in

whichl- Figurel is a side elevation of one spindle of a cop windertogetherwith such other parts ofthe winder as are necessary for a clearunderstanding of my invention; Fig. 2

'is a longitudinal sectional view taken through the axis of the spindlebearings; Fig. 3 1s a detail Sectional view taken on the l1ne'33 of Fig.1; Fig. 4 is a similar view taken on the line 4l of Fig. 1; and Fig. 5

is a detail section taken on the line 5-5 in Fig. 1 and showing theconstruction of the weight attaching plate.

In the machine embodying my invention the cop is formed upon ahorizontal rotating spindle 10, the yarn 11 being conducted to thespindle in the usual manner through the guide 12 over a frictional guidewheel 13 mounted upon a portion 14 of the frame of the machine,- andthence through the traversing guide 15 to thecop former 16.

The guide 15 is mounted upon an arm 17* secured to a shaft 18 extendinglongitudinally of the machine. It will be understood that in machines ofthis type a plurality of spindles lO are provided, mounted in parallelrelation throughout the length of the machine, and that a guide 15 andarm 17 is provided for each spindle. The shaft 18 to which the arms aresecured extends the entire length of the machine and is provided with anarm 19 connected by a link 20 to a crank pin 21 mounted on a disk 22 androtating with a shaft 23. The arm 19 may be provided with a slottedconnection with the link '20 by which the traverse of the guide 15 maybe adjusted.

The spindle 10 is mounted for both rotary and longitudinal movement inbearings 2 1, 25 and 26 as shown in Figs. 1 and 2. The

bearing 25 is provided with an adjustable cap which may be clampedtightly upon a sleeve 27 secured therein. This sleeveextends to theleftof the bearing 25 asshown in Fig. 2, and has looselymounted thereon apulley 28 which may be driven in any suitablemanner, as by the belt 29.Rotatably mounted within the sleeve 27 -is a second sleeve or bushing;30 provided with a square exterior portion 31, a reduced cylindricalportion 32, and a flange 33. The cylindrical portion32 rotates freely inthe bearing 26 while the flange 33 and the left hand end of thesquare'portion 31 prevent I Patented July 28,

longitudinal movement of the bushingrelative to the bearing. The righthand endof the square portion 31 likewise serves as a shoulder to limitlongitudinal movement of the pulley 28 on the sleeve 27. The bushing 30is furthermore provided with a square hole extending axiallytherethrough, within which the squareportion 34 of the spindle Thespindle,

10 is longitudinally movable. 10 is also provided with a reducedcylindrical portion 35 upon which is loosely mounted a sleeve 36 havingan end flange or plate 37. This plate, as clearly shown in Fig. 5, isprovided witha notch 38 and with a lateral projection to which issecured an eye 39. A weight 40 is secured to the eye 39 by a cord 41passing over a guide wheel 41- and tendsvat all times to move thespindlelO yieldingly toward the right in Fig. 1. A rib 41 is secured tothe frame of the machine and cooperates with the notch 38 to preventrotation of the sleeve 36 with the spindle .10, the plate 37 slidinglongitudinally along said rib as the spindle is moved to the left in theoperation of the machine.

Mounted upon the square portion 31 of the bushing 30 is a clutch member42 pro vided with a square hole and freely movable along the squaresurface of the bushing. The clutch member is provided with jaws 43cooperating with jaws 44 on the driving pulley 28 to transmit power fromthe pulley to the spindle 10.

The cop former 16 previously referred to is shown in Figs. 1 and 4 ashaving a partial conical shape and as being open upon its upper side.The cop former is secured to an arm 45 pivotally mounted on the frame ofthe machine at 46 and having a depending arm47 to which is secured oneend of a link 48.. The other end of the link 48 passes loosely through ahole 49 in an arm 50 (see Fig. 3) mounted upon a vertical shaft 51. Thisshaft has a bearing 52 in the frame of the machine and has secured toits upper end a yoke 53 provided with pins 54 extending into a circulargroove 55 in the clutch member 42. The rod 48 is yieldingly connected tothe arm 50 by a spring-56 as shown in Fig. .1., The arm '50 is heldagainst a collar 57 by the pressure of the spring 56 and a secondcollar58 is mounted upon the link 48 to receive the outward thrust of thespring 56.

The cop former 16 mounted upon the arm 45 is held in raisedvposition bya supporting member or brace 59 pivotally mounted upon a stud 60 securedto a bracket 61 mounted upon'the frameof the machine. The sup portingmember 59 is provided .with a laterally offset weighted handle oroperating arm 62, and the bracket 61 has a vertical extension .61 whichoverlies the arm 45 and limits upward movement thereof.

In the operation of my device the yarn is secured to the spindle whenthe latter is in extreme right hand position, asshown in Fig. 1, and thecop former is raised to the position alsoshown in that figure, when the.weighted handle 62 will automatically swing the supporting member 59under the arm 45, and maintain the cop former in operative position. Asthe cop former is raised the arm 47 will move the link 48 to the rightin Fig. 1, thus engaging the clutch member 42 iwith the driving pulley28 and starting the rotation ofthe spindle l0. Shouldthe teeth be indirect alinement with the teeth 44 when the link 48-is moved to theright, the

injury to the operating parts and the clutch member 42 will be pressedyieldingly to :ward the pulley 28 until the cooperating iteeth havemoved into proper relation with Ieach other. I

In my. device, as in other machines of this type, the yarn is movedbackward and foriward by the guide within the length of the cop former16 and as the cop is built up, the :conical end thereof bears againstthe former .and gradually pushes the spindle 10 toward ,the left,thereby raising the weight 40. \Vhen a sutlicient amount of yarn hasbeen wound upon the spindle the operator raises the handle 62, therebyremoving the supporting member 59 and allowing the cop former 16 todrop. This movement of the cop former is communicated through the link48 vto the clutch member 42, moving the latter to the left, and thusdisconnecting the driving mechanism. Furthermore, when the cop former 16is removed from operative posiltlOl'l the weight 40 is free to act uponthe spindle 10 and will return the same to initial position, the newlyformed cop moving to the right of the cop former and being in con-:venient position for dofing.

If desired the spindle may. be started in irotation after dofiing,before the yarn is attached thereto, the open upper side of the ,copformer affording access to the spindle :so that the yarn may be attachedwhile the spindle is in motion. This results in a material saving oftime on some classes of work, the yarn being more readily secured to thespindle when in rotation.

It is evident that many changes and modificationscan be made in theconstruction of 1ny.invention by those skilled in the art withoutdeparting from the spirit thereof and Ido not wish to be limited to thepre- ;cise construction herein disclosed, but

Whatl do claimis 1.
